Should fix ticket 11543
if input url is relative path, the seg-url would make absolute url twice in
get_content_url and open_input function
but it doesn't need make absolute url in open_input since we set it already

Hi everyone,
I’m trying to solve this issue https://trac.ffmpeg.org/ticket/11394.
This ticket shows that we need use `-seekable` and `-http_seekable` to control
the range header if send.
Because these options belong to different file(hls.c and http.c)
So I try to modify the http_seekable to se

Hi softworkz,
Thank you very much for your patient reply and kind suggestions. I am new to
the FFmpeg devel mailing list, and English is not my native language, so there
is still a lot for me to learn.
May I ask a question? How long does it usually take for a patch to be reviewed?

From: Jack Lau
The `dec_ctx->time_base` was incorrectly default set by avcodec_open2(), while
`enc_ctx->time_base` was derived from `dec_ctx->framerate`. This mismatch could
cause incorrect video duration in the output.
This patch corrects the issue by adjusting the `enc_ctx-&
culation
to account for `ticks_per_frame`, ensuring that the time base is consistent
between the decoder and encoder contexts.

Thank you for your reply. I understand that time_base is not used during
decoding, but the transcoding code calls av_packet_rescale_ts twice, once
before decoding and once after encoding, as shown below:
