Description
This has happened twice to me now, the first time I just deleted the file causing the crash, but since it's happened again I figured I should get off my lazy arse and generate a backtrace. Both times the file has been from my firewire connection. Everytime I hit refresh in mythweb recorded programs it crashes the slave backend that does the firewire recording. I am also pretty sure it causes the backend to crash when it generates the thumbnail after the recording finishes, because my backend went down hard last night right after this program was finished.
Starting program: /usr/bin/mythbackend -v all,nodatabase,noosd,nocommflag,nojobq ueue

Yep, it would crash the backed whether I tried from mythweb or mythfrontend. I did this several times till I was satisfied that it was definately handing on this one file.
I deleted the recording =(, it was actually the wrong channel. My firewire screwed up changing the channel which was a first for me. I never tried to play it in mythtv, mostly because I never thought of disabling previews, but it did play fine in mplayer.

Ok, without the recording we won't be able to diagnose the problem. My best guess is that this is due to the firewire recorder not properly processing the file and leaving some junk in there that ffmpeg crashes on. When you get another one of these files please reopen the ticket so we can address this.

Finally got another one using r8337. Same behavior as before, except it wasn't generated from a faulty channel change on the firewire. It got the right channel this time, but the program wasn't broadcast in HD, just SD. I disabled thumbnail previews and it plays fine in mythtv. I can reliably crash the backend now by just having it generate thumbnails from either the frontend or mythweb.
Same error in av_find_stream_info, let me know what else you need, will keep the file around this time.

I got this same issue today with a firewire recorded program and I think I see whats going on.
av_find_stream_info will segfault if there is a stream change within the mpegts packets its using to find the stream info. When a stream change happens the following trace happens
==15109== at 0x401B009: free (vg_replace_malloc.c:235) ==15109== by 0x4927C87: av_free (mem.c:128) ==15109== by 0x48BDF1E: flush_packet_queue (utils.c:1161) ==15109== by 0x48BDFA4: av_read_frame_flush (utils.c:1195) ==15109== by 0x48AAC3D: pmt_cb (mpegts.c:642) ==15109== by 0x48AA1A4: write_section_data (mpegts.c:263) ==15109== by 0x48AC488: handle_packet (mpegts.c:1523) ==15109== by 0x48AC71C: handle_packets (mpegts.c:1604) ==15109== by 0x48AD31F: mpegts_read_packet (mpegts.c:1892) ==15109== by 0x48BCCAD: av_read_packet (utils.c:702) ==15109== by 0x48BDA41: av_read_frame_internal (utils.c:1021) ==15109== by 0x48C04AC: av_find_stream_info (utils.c:2066)
flush_packet_queue() frees all AVPackets on ic->packet_buffer, but av_find_stream_info() has its own pointer (*ppktl) that points to the last AVPacket on ci->packet_buffer. The segfault is triggered next time av_find_stream_info() tries to append a packet to ic->packet_buffer using *ppktl.

The patch seems to have fixed it for me, it no longer crashed and it generated a correct thumbnail to boot. Thanks!

(In [8398]) Fixes #801, by applying patch from jwestfall at surrealistic dt net
This prevents avlib from crashing when a stream change occurs during the stream detection rutine. This can occur with default settings with the firewire or dbox2 recorders and could happen with the hdtvrecorder if you turn off 'wait-for-keyframe' and a stream change occurs within a couple milliseconds of the recording start.
Note:
See TracTickets
for help on using tickets.
Does this happen when you generate a preview by browsing the recording in mythfrontend?
Can you play these recordings in the frontend, assuming you disable previews?
