Hello all, Trying to compile the Chromium browser by myself, I encountered that compile fails due to variable declarations in ffmpeg_demuxer.cc in Chromium's source code.
In the file, the following call to av_packet_get_side_data() is made: size_t id_size = 0; uint8_t* id_data = av_packet_get_side_data( packet.get(), AV_PKT_DATA_WEBVTT_IDENTIFIER, &id_size); size_t settings_size = 0; uint8_t* settings_data = av_packet_get_side_data( packet.get(), AV_PKT_DATA_WEBVTT_SETTINGS, &settings_size); Compilation fails, however, with the error "no matching function found for av_packet_get_side_data", and the reason appears to be the following code in libavcodec/packet.h, line 626: uint8_t* av_packet_get_side_data(const AVPacket *pkt, enum AVPacketSideDataType type, #if FF_API_BUFFER_SIZE_T int *size); #else size_t *size); #endif If FF_API_BUFFER_SIZE_T is defined, this declaration expects *size to be of type int instead of size_t - because the size_t declaration sits in the #else branch of that declaration (instead of the #if branch as I (and apparently the Chromium developers) would have expected). But FF_API_BUFFER_SIZE_T, in my understanding, by its name should mean that size_t is used, however, the code in libavcodec/packet.h just handles it the other way round (ffmpeg version n4.4). This means you can only have *size of type size_t when FF_API_BUFFER_SIZE_T is NOT defined. Is this behavior intended? Or am I simply understanding something wrong here? Thank you very much for your help in advance and kind regards, Gerd _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
